WINDOW-ADJUSTING DEVICE.

To all whom it may concern:

Be it known that I, FRANK TOMSAK, a

d subject of the Emperor of Austria-Hungary,

residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Window- Adjusting Devices, of which the following is a specification.

' My invention relates to improvements in devices for adjusting windows and more particularly to devices of this character which are utilized to raise and-lower win- 1dows in motor, railway and street cars or the ike.

f In the present improvement the window is raised or lowered by turningahand crank in the proper direction and to render the turning action very easy a balancing spring is use to neutralize the weight of the window. v

The objects of the invention are to pro- /vide a simple, cheap and durable mechanism, to so arrange a balancing spring in connection with the same that the weight of the window is neutralized to enable the window to be raised or lowered very easily, and to detachably secure the window sash and its frame in place so that it may be removed when desired. These and other objects I accomplish as hereinafter set forth in the following description and as particularly pointed out in the appended claims, reference being had to the accompanying drawings in which an embodiment of my invention is shown.

In the drawings Figure 1, represents an inside face view of a fragment of the'door of an automobile body equipped with my improvement. Fig. 2, is an enlarged fragmentary vertical section through the door on line 2-2, Fig. 1. Fig. 3, is an enlarged fragmentary detail of the balancing spring and a section through the hand crank shaft on which it is'mounted. Fig. 4, is an enlarged horizontal section through the adjusting screw bar and window sash frame, also showing the adjustment block in the top plan and the pivotal locking leaves of the sash frame in two positions, its locked position in full lines and its unlocked position in Specification of Letters Patent.

ings in detail, like numerals designate corresponding parts.

My improved window adjusting mecha-' nism can be applied to automobiles, railway and street cars and other types of vehicles and also as well may be employed in buildings and dwellings and for all purposes for which an easy and quick operated device is desirable.

In the accompanying drawings, I have shown my improved devlce 1n connectlon with the side door of a closed motor car, 1

in dotted lines in Figs. 4 and 5. The two leaves 5, are turned from an unlocked position in alinement with the strip 4, as shown in dotted lines in Figs. 4 and 5, to their locked position as shown in full lines in said Figs. 4 and 5, and are retained in either position with a spring tension by a straight flat spring 7, which is fastened to the back of the strip by a screw 8 and has its extremities projecting over the edge of the leaves.

The door as shown is made hollow and is provided. with the usual top slot 9, through which thewin'dow sash slides and in the inher part of the door is fastened a supporting plate 10, an opening being cut to receive the same and the plate 10, being removably secured over the opening .by screws. A vertical screw bar 11, is arranged in the hollow of the door on the inner side of the path of the window sash and an adjustment block 12, formed substantially as shown in Fig. (i, has an internally screw threaded vertical opening 13 through which the screw bar passes.

The block 12 projectslaterally outward and beneath the window sash and has a flat bar 14, fitted in a horizontal slot in its outer side, the ends of said bar extending beyond the block and constituting locking projections which fit within the slots 6, of the locking leaves of the window frame and detachably fasten the window to the adjust- Patented Dec. 5, 1916.

\journaled in a'bearing 16, as shown in F ig. 2, and a bevel gear wheel 17, is rigidly mounted on the bar just below the upper bearing 15. I A short horizontal shaft 18, is journaled in'a bearing boss 19, attached to the plate 10, and located at about the center of said plate and a hand crank is mounted on the proj ecting outer end of said shaft which carries 10a turning handle 21'.- As shown in Fig. 2, the turning handle may be pivoted to the wheel so that it can be folded within the wheel when not in use. Upon the inner extremity of the shaft 18, a large miter gear 5 Wheel 22,is mounted which meshes with the bevel gear wheel 17 at the upper extremity of the screw bar.

The gear wheel 22, in structure is of a thin disk like form with a tubular center 2 hub 23, and an-outer circular flange 24, thus providing an annular space 25, which is closed on its inner side by the plate 10, as shown in Fig. 2. Within the space 25, a spirally coiled balancing spring 26, is ar 25 ranged which has its inner end 27, bent inwardly and fastened in a slot in the hub 23. The outer end of the spring is secured to the plate 10 by a, screw 28' The purpose of the balancing spring is to counterbalance the 30 weight of the window and thus render the operation of raising and lowering the same quick and easy.

When it is desired to adjust a window equipped with-my improvement, the operator turns the hand crank in the proper direction which rotates the screw bar and vertically moves the adjustment block thereon, thereby moving the window in the direction required. The window frame is quicklyde- 40 tached from the adjustment byturnin'g the locking leaves from their locking position to, their non-locking position and then lifting the window out.

While I have illustrated and described a '45 preferred form of construction for carry- 1 mg my invention into effect, the same is capable of a wide range of variations, alterations, modifications and change without departing from the'spirit of the invention, I

therefore do not wish to be limited to the construction shown and described in the appended claims, but desire to avail myself of all such variations, alterations, modifications and changes as fairly fall within the scope of the appended claims or may be construed to come within the same by involving the doctrine of equivalents.

What I claim as my invention and desire to secure by-Iretters Patent is: 1. In a device of the class described, a v window having a frame, pivotal locking leaves secured to said frame, a screw bar an adjustment block on said screw bar having projecting parts adapted to engage the looking leaves, and means for rotating the screw 2. In a. device of the class described, a window having a frame, pivotal locking leaves secured to said frame, a screw bar, an adjustment block on said screw bar having projecting parts adapted to engage the locking leaves, and" gear means for rotating the screw bar. I

3. In' a device of the class described, a

hollbw frame, a window slidably mounted in said hollow frame, movable locking devices securedto said frame, an adjustment block connected to said window detachably engaged by the'lockin devices, a vertical screw bar. upon which tdie adjustment block is threaded, a gear wheel on said screw bar,

a large miter gear wheel meshing with t 'e gear wheel and arranged in the hollow frame on one side of the path of travel of the wiltdow, a short horizontal shaft upon which the miter gear wheel is mounted and a hand crank also mounted on saidhorizontal shaft.

a large miter gear wheel meshing with the gear wheel and arranged in the hollow frameon one side of the path of travel of the win- 'dow; said large miter, gear wheel being dished, a spiral counterbalanciirgspring located in the space between-the miter gear wheel and the side wall of the hollow frame and connected at its respective ends to the miter gear wheel and the hollow frame, a short horizontal shaftvupon which the miter gear wheel is mounted and a hand crank also mounted on saidhorizontal shaft.

5. In a device of the class described, a hollow frame, a window slidably mounted in said hollow frame, pivotal lockingleaves 1 10 secured to said frame, an adjustment block connected to said window, and having projecting parts adapted to be detachably engagedby the pivotal locking leaves, a vertical screw bar upon which the adjustment block is threaded, a gear wheel on said screw bar, a large miter gear wheel meshing with the gear wheel and arranged in the hollow frame on one side of the path of travel of the". window, a short horizontalshaft upon which the miter gear wheel is mounted and a hand crank also mounted on said horizontal shaft.

In testimony whereof I have afiixed my signature.
